There is a new doping case in Germany's professional football. Doping control officers found a cortisone substance in Francois Marque's blood. His club 1. FC Saarbrücken (third division) confirmed the positive test of the French player, says [German public TV ARD](http://www.sportschau.de/fussball/bundesliga3/marque100.html).

More than 100 positive doping tests have been discovered in Portuguese football over the last ten years. That’s quite remarkable and by far the record number in European football. What’s the reason for so many positive tests? The answer is to be found in the Portuguese control system.

The German Football Federation’s tribunal has ruled the positive test of Francois Marque as a doping offense. However, the defender of third division side Saarbrücken FC has been only banned for six matches as he didn’t use a classic performance enhancing product. The DFB published the verdict on its website (Press Release in German).

Doping controls during football world cups are extremly ineffective. Not a single player has been tested positive in the past four world cups. And it could get even worse in Brazil as there is the samples might not be able to analysed in time.

FIFA announced one new rule in the run-up to the World Cup 2014: All players of all teams should be tested with blood and urin for the so-called biological profile prior to start of the competition. We are trying to track every doping control made by FIFA prior to the upcoming World Cup. Help us to miss nothing and get the complete picture.

FIFA had a keen plan: Every player at the World Cup was supposed to be tested at least once before the start of the tournament. Well, it didn’t happen. The rather large number of 62 players (that’s almost three complete squads) were not tested before the World Cup. No problem for FIFA, they just tested those players during the tournament. Another issue is the travel time of doping tests. That was much longer than expected and a positive test could have led to severe consequences. Taken all this into account, we had pretty good reasons to look for some weak spots.

Tomorrow we at fussballdoping.de are starting a newsletter. From time to time, we'll keep you updated about our work and our results by email.

Almost eight percent of all European football stars could be on steroids. That is the result of an official study founded by UEFA. More than 4000 tests from close to 900 professional players habe been re-tested. The values of close to every twelth player were suspicious. Since the tests were anonymised, none of the 68 players will be charged. Still, the times of "doping is no problem in football" are over. We took a look at the study – and we show you where you can find it yourself.

Every time Hans-Wilhelm Müller-Wohlfahrt declares a diagnosis the world of football believes him. Athletes from all over the world fly to Munich to get treated by the team doctor of Bayern Munich and the German national federation DFB. But experts critizise his work and his advertisement for food supplements. How does Hans-Wilhelm Müller-Wohlfahrt work?

The doping tests in Europe's top football leagues are full of holes. Still, there have been more than 300 doping cases in the last couple of years. An investigation for Spiegel Online done by fussballdoping.de looked into the different anti doping systems in European football.
